Why Switzerland is keeping interest rates at zero while others tighten

0% is still the number shaping Swiss borrowing, saving and housing costs. The Swiss National Bank has kept its key interest rate at zero for more than a year, even as major central banks maintain much higher settings. The next test comes on September 24, 2026, when the SNB will decide whether domestic conditions justify a change.

The gap is clear. The European Central Bank's rate stands at 2.25%, while US rates range between 3.5% and 3.75%. The ECB is widely expected to raise its rate at its September 10 meeting, according to the source article. Those moves have intensified scrutiny of Switzerland's unusually cheap money.

For households, the policy filters through to mortgage offers, savings accounts and pension returns. Ten year mortgages averaged 1.9% in Switzerland, according to Comparis. Borrowers still face higher costs than the SNB's headline figure suggests, because banks price loans according to market funding, risk and the term of the mortgage.

The SNB's decision will also be watched in financial centres from Zurich to Geneva. Investors are weighing whether Switzerland can preserve low rates while the franc remains strong and inflation stays subdued.

Swiss inflation was just 0.8% in August 2026. That figure gives the SNB room to keep rates low while other central banks respond to stronger price pressure. Average inflation across European countries stood at 2.9% in July, and the US rate was 3.4%, according to the source article.

Central banks use interest rates to restrain demand and prevent inflation from becoming embedded in wages, services and expectations. When price growth is weak, aggressive tightening can create unnecessary damage by raising the cost of credit for households and companies.

Caroline Hilb, head of investment and pension provision at Raiffeisen Bank, said Switzerland's low inflation and strong franc reduce the need for a rate increase. “At present, inflationary pressure is still too low and the Swiss franc is too stable for there to be any need to adjust interest rates,” she said.

Daniel Kalt, UBS chief economist, reached a similar conclusion. “Inflation is still too low for that,” he said when assessing whether Switzerland faced pressure to raise rates. The figures explain the divergence. The SNB is responding to Swiss conditions, even when the policy choices of Washington and Frankfurt affect exchange rates, capital flows and imported goods.

The franc remains one of the SNB's most important policy variables. Switzerland's currency has a long reputation as a safe haven, attracting demand when investors seek stability. A strong franc reduces the cost of imported energy, food and manufactured goods, helping contain consumer prices.

That currency effect changes the interest rate calculation. A rate increase could support the franc further, making Swiss exports more expensive for customers abroad. Swiss manufacturers, tourism operators and companies with international revenues would then face pressure even if domestic inflation remained limited.

Caroline Hilb said the franc was “too stable” to require a policy adjustment. Her assessment reflects the SNB's broader balancing act. The central bank must monitor inflation inside Switzerland while also considering how interest rate differences influence the currency and financial markets.

The exchange rate does not insulate Switzerland completely. Hilb noted that higher US rates can push Swiss rates upward because financial markets operate across borders. Swiss mortgage pricing has already risen slightly, although the increase has been weaker than in many European countries and in the United States.

For exporters in cantons such as Vaud, Basel City and Zurich, currency movements can matter as much as the SNB's headline rate. A stable franc offers price relief for consumers, while its strength can narrow margins for firms selling abroad.
